AJAX SSH登陆验证回调函数错误问题
问题精简如下:
javascript中:

function login(){
var url="Login_login";
var params={"id":1,"password":"110"};
//ajax()方法
jQuery.ajax({
            type: "get",
            async: true,
            url: url,
            data: params,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            cache: false,
            success: function (data) {
             alert("success "+data.id);
            },

            }

private boolean isSuccess;
//不用new,用spring容器提供
//private UserService userService=new UserServiceImp();过时
private UserService userService;
private ApplicationContext applicationContext=null;
private String result;
public String login(){
/*测试一下*/
System.out.println("id="+this.getId()+"password="+this.getPassword());

// applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
// userService = (UserService) applicationContext.getBean("UserServiceImpl");
// isSuccess=userService.checkIdAndPassword(id, password);

 Map<String, Comparable> map = new HashMap<String, Comparable>();  
 map.put("id", this.getId());  
         map.put("password",this.getPassword()); 
         JSONObject obj = JSONObject.fromObject(map);
         result = obj.toString();  
         System.out.pri
